The Queen inherited the mother of all art collections—7,000 paintings, 30,000 watercolors, and half a million prints, to say nothing of sculpture, furniture, and jewelry—but she shows only a tiny fraction. The few works (budget 1 hr.) are undoubtedly exceptional (one of the world’s few Vermeers, a Rubens’ self-portrait given to Charles I, glittering ephemera by Fabergé), but they’re not the cream of what she owns. There’s more exciting stuff to be had for free at the National Gallery. The Gallery and the Royal Mews can be seen on a joint ticket (£17.70 adults, £9.70 children 5–16, £16.10 seniors/students).
